Site requirements
The printer must be kept in a proper location to maintain the performance level that has been set at the factory. In particular, be sure that the environment adheres to the specifications listed in this chapter.
Below are recommendations for the printer location and placement.
Make sure the printer has the following:
●a well-ventilated, dust-free area
●a hard, level surface (not more than a 2° angle):
•for the HP Color LaserJet 4600, 4600n, and 4600dn, the surface must support 37 kg (81 lb)
•for the HP Color LaserJet 4600dtn and 4600hdn, the surface must support 44 kg (97 lb)
●a level surface that supports all four corners of the 500-sheet paper feeder
●a constant temperature and humidity. (Do not install near water sources, humidifiers, air conditioners, refrigerators, or other major appliances)
Make sure to keep the printer away from the following:
●direct sunlight, dust, open flames, or water
●the direct flow of exhaust from air ventilation systems
●magnets and devices that emit a magnetic field
●areas subject to vibration
●walls or other objects. There must be enough space around the printer for proper access and ventilation. See Figure 1-4 on page 23.
Space requirements
The printer must have the following amounts of space above and around it.

Chapter 1 Printer description 27 |
You can use many types of paper and other print media with this printer. This section provides guidelines and specifications for selecting and using different print media.
Before purchasing any media or specialized forms in quantity, verify that your paper supplier obtains and understands the print media requirements specified in the HP LaserJet Family Print Media Guide. The guide is available through Hewlett-Packard Customer Support (HPCS). See page 47 for ordering information.
It is possible that media could meet all of the guidelines in this chapter and still not print satisfactorily. This may be a result of abnormal characteristics of the printing environment or of other variables over which Hewlett-Packard has no control (for example, extremes in temperature and humidity).
Hewlett-Packard recommends testing any media before buying it in large quantities.
CAUTION Using media that does not conform to the specifications listed here and in the HP LaserJet Family Print Media Guide can cause problems that require service. This service is not covered by the Hewlett-Packard warranty or service agreements.
For optimum results, use conventional 75 g/m2 (20 lb) xerographic paper. Verify that the paper is of good quality and is free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, curls, or bent edges. Avoid fanning the print media before loading it into the paper trays.
